hello,

as i have seen in coaxial helicopter rotors the second swashplate which works for upper rotor is located between lower and upper rotors but in sikorsky x2 it is not visible between the rotors certainly upper rotor swashplate is inside

please tell where is its location and also how does it perfomance for cyclic and collective pitch??


thanks alot

There is a public domain paper out there on the X2 predecessor. Dave Jackson's website has a link to it.
